Infant Undergarment

ABSTRACT

The infant undergarment includes a rear panel extending down from a neck curve and between lateral seams. A lower flap defines a lower portion of the rear panel which has lateral edges defined by leg curves giving the lower flap an hourglass form. A lower edge of the lower flap can be rotated up between legs of an infant and fastened back to other portions of the infant undergarment. A right front flap and left front flap extend from lateral seams of the rear panel to lateral edges of the front flaps which are adjacent to each other. Front fasteners adjacent these lateral edges allow for removable attachment of these lateral edges of the right front flap and left front flap to each other. The corner fasteners and front fasteners utilize complemental fasteners which can be removably attached from each other for convenient removal and replacement of the infant undergarment.

FIELD OF THE INVENTION

The following invention relates to infant undergarments primarily for the torso of an infant and to cover a diaper thereof. More particularly, this invention relates to infant undergarments which can easily be placed on and off of the infant using multiple complemental fasteners.

BACKGROUND OF THE INVENTION

Infant undergarments come in a variety of configurations, including configurations generally similar to those for children. A t-shirt undergarment is known which has a neck opening and sleeve openings as well as a torso opening at a lower end. Various forms of lower body undergarments are also known, such as short and long leg underpants.

One type of infant undergarment is known as a “onesie.” A typical onesie is similar to a t-shirt except that it has a pair of lower flap which are removably attachable to each other between the legs of the infant. This openable lower flap allows for a diaper to be changed without removing the undergarment. Typically, the lower edge of the lower flap is attached to the front lower edge of the undergarment through a series of snaps (typically three) between the lower edge of the lower flap and the lower edge of the front portion of the undergarment.

Other details of the undergarment are that it will often have an enlarged neck opening to make it somewhat easier to pull on over the head of the infant. While known prior art onesies are satisfactory in many situations, it can be difficult to change an infant out of a onesie in certain circumstances. For instance, when the infant is sleeping and it is desirable to change the infant's clothes without awaking the infant, this is difficult to do with a typical prior art onesie, because the entire garment must be lifted up over the head and arms of the infant. Also, when an infant has a diaper which has not successfully contained excrement and/or urine, so that various portions of the onesie are contaminated, it is then necessary for the undergarment to be lifted over the head of the infant when it is in its soiled state. This often then requires complete bathing of the infant. Accordingly, a need exists for a onesie type infant undergarment which provides the convenience of a onesie but can be more easily put on and taken off of an infant without requiring the entire garment to be lifted over the head of the infant.

SUMMARY OF THE INVENTION

With this invention, an infant undergarment is provided which has some features generally similar to that of a “onesie” type undergarment, but which also is openable along a front flap thereof from a neck opening down to a front lower edge of the undergarment at a front flap.

The undergarment generally includes a neck opening and a left sleeve and right sleeve configured to allow the neck and head, as well as the right arm and left arm of the infant to extend out of the undergarment. A torso portion of the undergarment extends down from the neck opening and the left and right sleeves. This torso portion extends down to a front lower edge and a rear lower edge.

The rear lower edge extends significantly further down than the front lower edge. In a preferred embodiment this extension of the rear lower edge is in the form of a lower flap which can be contoured such as with an hourglass contour to be wider at the rear lower edge and adjacent the front lower edge than at a lower curve portion. While the undergarment could have an opening and fasteners at this lower curve (FIG. 1) most preferably the rear lower edge is configured to fasten to the front lower edge (FIG. 1). The hourglass shape or other configuration of the lower flap accommodates a left leg opening and a right leg opening along lateral sides of the lower flap through which legs of the infant can extend.

Fasteners are provided along the rear lower edge and along the front lower edge. These fasteners include in a preferred embodiment two corner fasteners and a middle fastener. The corner fasteners are generally at hips of the infant and the middle fastener is near a navel of the infant.

These fasteners can be any of a variety of different fasteners including snaps, buttons, hook and loop fasteners (such as those provided under the trademark VELCRO by Velcro Industries B.V. of the Netherlands), or other fasteners. Most preferably, the fasteners are hook and loop type fasteners with complemental hook and loop patches. One of the complemental patches is located at the corners and middle of the rear lower edge and complemental hook and loop fastener patches are also provided at the hip and navel portions of the front lower edge with a similar spacing to the hook and loop fastener patches provided adjacent the rear lower edge. As an alternative, a single continuous fastener in the form of hook and loop fastener portions could be provided along the rear lower edge and along the front lower edge.

The fastener on the rear lower edge is on an inside of the garment. The fastener on the rear lower edge is on an outside of the garment. Thus, the rear lower edge overlaps on top of the front lower edge when the fasteners are going together. To ensure infant comfort, preferably the softer half (typically the “loop half”) of the complemental hook and loop fasteners is provided adjacent the rear lower edge, so that if any portion of these fasteners on the inner surface thereof comes in contact with skin of the infant, it is not as irritating as the hook portion. These rear lower edge and front lower edge fasteners can be opened to allow access to a lower end of the garment, such as to change an infant's diaper. The fasteners can then later be reutilized to close up the lower edge of the garment once again.

A front flap on a torso portion of the infant undergarment is provided which is selectively openable and closable. In particular, the front flap is configured so that it overlaps slightly from a left side over onto a right side (or vice versa). Overlapping lateral portions of this front flap are configured with fasteners, with fastener halves located on an outside surface of the right portion of the front flap and on the inside surface of the left portion of the front flap (or vice versa). These fasteners can be any form of fasteners similar to those described above, but most preferably are in the form of hook and loop fasteners.

Most preferably, this front flap extends entirely from the front lower edge to the neck opening so that the entire torso portion of the undergarment can be opened off of the torso of the infant. Thus, when the undergarment is to be removed from the infant, the only portion of the undergarment which must be navigated with some difficulty off of the infant is the removal of the infant's arms through the sleeves and arm openings. This can be achieved without requiring that the entire undergarment be lifted up over the head of the infant. Thus, if a lower portion of the undergarment is soiled, this lower portion can stay away from the head and torso of the infant, greatly increasing the simplicity with which a diaper containment failure can be adequately addressed. Similarly, a sleeping infant can be more readily changed out of the undergarment and remain sleeping in at least some instances. A visual access slot is provided in the rear panel of the torso portion, strategically located just above where the top rear edge of the diaper would be. An individual can use this slot as a visual inspection port to see if a diaper change is needed.

Finally, it is also conceivable that fasteners could be provided along an upper edge of the sleeves, such as through snaps or other fasteners such as those described herein, so that even the arms of the infant do not need to be navigated through the sleeves and arm openings for complete removal of the undergarment from the infant.

OBJECTS OF THE INVENTION

Accordingly, a primary object of the present invention is to provide an undergarment for an infant which is easy to put on and take off of the infant.

Another object of the present invention is to provide an infant undergarment which can be removed without pulling large portions of the undergarment over a head of the infant.

Another object of the present invention is to provide an infant undergarment which can be put on and removed with a high likelihood that the infant can be kept sleeping during the undergarment removal process.

Another object of the present invention is to provide a method for putting on and taking off an infant undergarment.

Other further objects of the present invention will become apparent from a careful reading of the included drawing figures, the claims and detailed description of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures, reference numeral 10 is directed to an infant undergarment configured to be worn by an infant I and which is particularly configured to be easy to put on and take off to facilitate diaper changes, clothing changes, etc., and especially while allowing a sleeping infant I to remain sleeping during such a change.

In essence, and with particular reference to FIGS. 1, 2 and 7, basic details of the infant undergarment 10 of this invention are described, according to a preferred embodiment. The undergarment 10 includes a torso portion which is formed of a rear panel 20 and a pair of front flaps including a right front flap 50 and a left front flap 70. A lower portion of the rear panel 20 transitions into a lower flap 30 which is shaped to pass between legs L of the infant I and wrap back up for attachment to lower portions of the front flaps 50, 70. The torso portion also includes a right sleeve 40 and left sleeve 60 for wearing about arms A of the infant I. The rear panel 20 includes a strategically located visual access slot 80 which allows for visual inspection in a downward direction above a rear edge of a diaper to determine visually whether a diaper change is required. Complemental fasteners are strategically located to hold the lower flap 30 to the left and right front flaps 50, 70 and to hold the left and right front flaps 50, 70 together in a removable fashion. The resulting undergarment 10 thus does not need to be lifted up over a head of the infant I for removal thereof or for putting the infant undergarment 10 onto the infant I.

More specifically, and with continuing reference to FIGS. 1-3, 6 and 7, particular details of this invention are described, according to this preferred embodiment. The infant undergarment 10 is a flexible fabric structure which is formed of one or more sections of fabric strategically sewn together to form a geometry such as that depicted in FIGS. 1, 2 and 8. In particular, this flexible fabric is cut and then sewn into a shape including the rear panel 20 with the lower flap 30 at a lower portion thereof and with the right sleeve 40 and left sleeve 60 at upper portions of the undergarment 10, with the right front flap 50 and left front flap 70 extending from lateral sides of the rear panel 20.

The particular geometry of the rear panel 20 is shown best in FIG. 7. A neck curve 22 defines an upper edge of the rear panel 20. Various seams define perimeter portions of the rear panel 20 depending on how the overall infant undergarment 10 is constructed. In the embodiment depicted, lateral seams 24 define lateral edges of the rear panel 20. In one simple form of the invention these lateral seams 24 extend all the way up to the right sleeve 40 and left sleeve 60. Optionally, seams can be provided on an uppermost portion of the rear panel 20 extending from the right sleeve 40 and left sleeve 60 to the neck curve 22. Alternatively, continuos fabric can wrap over upper portions of the right sleeve 40 and left sleeve 60 so that upper portions of the rear panel 20 wrap over the right sleeve 40 and left sleeve 60 and transition into the right front flap 50 and left front flap 70.

A lower portion of the rear panel 20 transitions into the lower flap 30. The lower flap 30 has a somewhat hourglass shape with leg curves 32 on lateral sides thereof which cause a width of the lower flap 30 to transition from a width matching a width of the rear panel 20 to a lesser width (preferably less than half of full width) as the leg curves 32 curve toward each other, and then transitioning back to a greater width as the leg curves 32 continue to curve away from each other and approach the lower edge 34 of the lower flap 30. Typically, the leg curves 32 terminate and lateral edges of the lower flap 30 continue parallel to each other and at constant widths down to a lowermost portion of the lower flap 30 defined by the lower edge 34. As can be seen in FIGS. 1 and 2, this lower portion of the lower flap 30 below the leg curves 32 and above the lower edge 34 defines a region which can be folded up between legs L of the infant I (FIG. 1) and then overlap lower portions of the right front flap 50 and left front flap 70 on a front side of the infant I.

Fasteners are utilized to hold the lower flap 30 in this closed position in a removable fashion. A preferred form of such fasteners include corner fasteners 26 strategically located adjacent to the lateral seams 24 of the rear panel 20 on portions thereof most distant from the right sleeve 40 and left sleeve 60. In one embodiment, two (or more) corner fasteners 26 are provided with one closer to the lateral seam 24 and the other(s) further from the lateral seams 24 and further toward a center of the rear panel 20. In this way, tighter and looser options can be selected for fastening the lower flap 30 closed. A middle fastener of similar construction can also be provided if desired, typically at a midpoint between the corner fasteners 26, 36. Complemental portions of this fastener 36 are also provided on portions of the lower flap 30 adjacent to the lower edge 34 and at lateral edges of the lower flap 30 adjacent to the lower edge 34 of the lower flap 30. These complemental fasteners are referred to as corner fasteners 26, 36 in that they are located at a lower corner of the rear panel 20 and at a corner of the lower flap 30 where lateral edges of the lower flap 30 come together with the lower edge 34.

The corner fasteners 26, 36 are complemental to each other. In the embodiment shown, the first corner fastener 26 (or series of corner fasteners 26) is on the rear panel 20 and a second corner fastener 36 is on the lower flap 30. The complementary nature of these fasteners 26, 36 can be provided in a variety of different ways. In one embodiment these corner fasteners 26, 36 are in the form of hook and loop fasteners with one of the fasteners 26, 36 providing hooks and the other of the corner fasteners 36, 26 in the form of loops, and with the hooks and loops configured to connect together in a removable fashion because the hooks are somewhat flexible. One such hook and loop fastener is provided under the trademark VELCRO by Velcro Industries B.V. of the Netherlands.

Other forms of complemental corner fasteners 26, 36 could include snaps or buttons (or magnets, zippers, etc.). In the case of snaps two physical structures would be provided, one with a knob and one with a recess, and with the knob being able to snap into the recess in a manner releasably holding the knob in the recess so that the snaps facilitate removable attachability for the fasteners 26, 36. In the case of buttons, one of the fasteners 26, 36 would be in the form of a button sewn to the fabric at the location where the button is to be provided, and the other of the fasteners 26, 36, would be formed as a button hole in the fabric of an appropriate size to allow the button to be removably fastened thereto. Other forms of complemental fasteners could alternatively be provided for the corner fasteners 26, 36.

When the corner fasteners 26, 36 are in the form of hook and loop fasteners, preferably the hook portion is on the corner fasteners 26 and the loop portion is on the corner fasteners 36. In this way, the softer loop fasteners will face toward the infant I so that if somewhat out of alignment and come into contact with the infant I, relatively soft loops would provide this contact, rather than the somewhat abrasive hooks. The shape of the patches forming such hook and loop fasteners can vary, with circular and rectangular shapes being two of the available options for the hooks or the loops.

Referring primarily to FIGS. 2, 3, 5 and 6, the right sleeve 40 and left sleeve 60 include a right arm opening 42 passing therethrough and a left arm opening 62 passing therethrough. These arm openings 42, 62 are sized sufficiently large to allow the arm A of the infant I to pass therethrough. Most typically the fabric is sufficiently flexible and the arm openings 42, 62 are sufficiently large so that one of the arms A of the infant I can be passed therethrough either “hand first” or “elbow first” with a forearm and upper arm of the infant I able to pass through the opening 42, 62 and then be pulled entirely through the opening 42, 62, so that the arms A of the infant I can be passed through the openings 42, 62 in a variety of different ways depending on the comfort of the infant. In other embodiments, the openings 42, 62 of the sleeves 40, 60 can be more “fitted” with smaller size and less flexibility and still function acceptably according to this invention. The sleeves 40, 60 can be “long sleeves” if desired either completely covering arms A and hands or just arms A. As an option, such long sleeve (or short sleeves) can have sleeve stitching circumscribing the sleeves 40, 60 to attach them to other portions of the garment.

The right front flap 50 and left front flap 70 extend from the lateral seams 24 of the rear panel 20 (or seamlessly if desired) toward each other. The right front flap 50 terminates at a lateral edge 52 most distant from the rear panel 20. The left front flap 70 extends to a lateral edge 72 most distant from the rear panel 20. These lateral edges 52, 72 are positioned based on a width of the right front flap 50 and left front flap 70 which is preferably selected to match a size of the infant I so that the lateral edges 52, 72 are directly adjacent each other and slightly overlap when placed upon the infant I.

The lateral edge 52 includes a front fastener 53 thereon. The lateral edge 72 includes a front fastener 73 thereon. These front fasteners 53, 73 preferably are similar in nature to the corner fasteners 26, 36. Thus, if the corner fasteners 26, 36 are in the form of hook and loop fasteners, the front fasteners 53, 73 are also hook and loop fasteners. Similarly, the front fasteners 53, 73 could be formed of snaps, buttons or other fasteners generally matching the character of the corner fasteners 26, 36 for the infant undergarment 10. Alternatively, different types of fastening technology could be utilized for the front fasteners 53, 73 than is utilized for the corner fasteners 26, 36. For instance, the lateral edges 52, 72 could be fitted with a zipper fastener and zip open and closed.

In the figures, the front fasteners 53 are depicted as a circular patch of hook and loop fastener material. The front fasteners 73 are depicted as a rectangular patch of loop portion of hook and loop fastener material. The front fastener 73 is on a lower surface of the left front flap 70 adjacent the lateral edge 72 and the front fastener 53 is located on an outer surface of the right front flap 50 adjacent the lateral edge 52. Broken lines are thus utilized to depict the front fastener 73. When these fasteners 53, 73 are brought into proximity to each other, they connect together in a removable fashion. Other shapes could be provided for these patches of hook and loop fastener material.

With particular reference to FIG. 7, details of the visual access slot 80 are described. The visual access slot 80 has a top edge 82 parallel to a bottom edge 84. These edges 82, 84 are preferably directly adjacent each other, but formed with the fabric of the infant undergarment 10 with sufficient flexibility so that this slot 80 can be easily opened by spreading the top edge 82 away from the bottom edge 84 slightly. A hole can be cut in the rear panel 20 to form the slot 80 or a horizontal seam can extend a full width of the garment 10 with the seam open at a midpoint to form the slot 80. Such spreading allows an individual to have visual access through the slot 80, particularly in a downward direction just above an upper edge of a diaper worn beneath the infant undergarment 10. A view can be made downward on the lower torso of the infant and inboard of the diaper to determine if the infant has soiled the diaper or not. As an alternative or in addition to visual inspection, an individual can reach through the slot 80 and determine to some extent if there is wetness in the diaper or not. The visual access slot 80 thus facilitates a determination of whether or not an infant requires a diaper change and the severity of the need for such a diaper change.

With particular reference to FIG. 8, an alternative embodiment for the infant undergarment 10 is depicted where the corner fasteners 26, 36 are replaced with an alternative front lower hook fastener strip 126 and an alternative lower flap loop fastener strip 136. Rather than discreet locations for the corner fasteners 26, 36, an entire elongate strip 126, 136 is provided for attachment together and detachment, when the infant undergarment 10 is being placed on or removed from an infant I (FIG. 1). Similarly, in this embodiment depicted in FIG. 8, alternative right front hook fastener strips 153 and alternative left front loop fastener strips 173 are utilized of a continuous nature for securing the lateral edges 52, 72 of the right front flap 50 and left front flap 70 together, rather than discreet locations for the front fasteners 53, 73 as depicted in other embodiments.

In use and operation, and with particular reference to FIGS. 1, 2 and 8, details of the use and operation of the infant undergarment 10 are described, according to this preferred embodiment. Often an infant I is sleeping but still requires a change of an undergarment. For instance, if the infant I has soiled a diaper and/or has soiled the undergarment, it may be desirable to change the undergarment 10. However, if the infant I is sleeping it is desirable to keep the infant sleeping. Prior art undergarments typically require pulling the undergarment over the head of the infant I and it is difficult to keep the infant sleeping and/or clean during such a procedure.

With this invention, the undergarment is both placed on the infant I and removed from the infant I without ever requiring the undergarment to be pulled over the head of the infant I. Rather, and when putting the undergarment 10 on the infant I, one can initially place a left arm through the left sleeve 60 and a right arm A through the right sleeve 40. The rear panel 20 can be generally slid under the infant I carefully with the lower flap 30 beneath the legs L of the infant I. The lower flap 30 can then be wrapped up between the legs L until it is parallel with the rear panel 20 and the corner fasteners 26, 36 can be utilized to secure the lower flap 30 to the rear panel 20. Finally, the right front flap 50 and left front flap 70 can be brought together and the front fasteners 53, 73 utilized to complete the attachment of the infant undergarment.

While the legs and torso of the infant I are manipulated slightly during this process, the undergarment 10 never needs to be pulled over a head of the infant I to pull the head H through a neck opening. When the infant undergarment 10 is to be removed, first the corner fasteners 26, 36 can be detached and the lower flap 30 rotated downward between the legs L of the infant I into a position parallel with the rear panel 20. If only a diaper change is to be effectuated, the diaper change can then be performed and then the lower flap 30 reattached to the rear panel 20. If the infant undergarment 10 is to be completely removed, the lateral edges 52, 72 have the front fasteners 53, 73 separated therefrom and the right front flap 50 and left front flap 70 are rotated away from each other until they are generally parallel with the rear panel 20. Finally, the rear panel 20 can be slid, typically to one side and the arms A of the infant can be brought through the sleeves 40, 60 to complete the infant undergarment 10 removal process. Often a sleeping infant I can remain sleeping during this procedure.

This disclosure is provided to reveal a preferred embodiment of the invention and a best mode for practicing the invention. Having thus described the invention in this way, it should be apparent that various different modifications can be made to the preferred embodiment without departing from the scope and spirit of this invention disclosure. When structures are identified as a means to perform a function, the identification is intended to include all structures which can perform the function specified. When structures of this invention are identified as being coupled together, such language should be interpreted broadly to include the structures being coupled directly together or coupled together through intervening structures. Such coupling could be permanent or temporary and either in a rigid fashion or in a fashion which allows pivoting, sliding or other relative motion while still providing some form of attachment, unless specifically restricted.
